Wafer Level Package

Abstract The demands of electronic packages toward lower profile, lighter weight, and higher density of I/O lead to rapid expansion in the field of flip chip, chip scale package (CSP) and wafer level packaging (WLP) technologies. The urgent needs of high I/O density and good reliability characteristic lead to the evolution of the ultra high-density type of non-solder interconnection such as the wire interconnect technology (WIT). The new technology using copper posts to replace the solder bumps as interconnections shown a great improvement in the reliability life. Moreover, this type of wafer level package could achieve higher I/O density, as well as ultra fine pitch. This research will focus on the reliability analysis of the WIT package structures in material selection and structural design, etc. This research will use finite element method to analyze the physical behavior of packaging structures under thermal cycling condition to compare the reliability characteristics of conventional wafer level package and WIT packages. Parametric studies of specific parameters will be performed, and the plastic and temperature dependent material properties will be applied to all of the models.

Wafer Level Package

The market of Connectivity, Internet of Things (IoT), Wearable and Smart industrial applications leads Fan Out Wafer Level Package (FOWLP) technologies to a promising solution to overcome the limitation of conventional wafer level package, flip chip package and wire bonding package in terms of the solution of low cost, high performance and smaller form factor packaging. Moreover, FOWLP technology can be extended to system-in-package (SiP) area, such as multi chip 2D package and 3D stack package types. nepes Corporation has developed several advanced package platforms such as single, multi dies and 2D, 3D packaging by using FOWLP and embedding technologies. To fulfill SiP (system-in-package) with FOWLP, several dies and components have been embedded into one package which offers 40~90 % of volumetric shrink compared to the current module system with the flexibility of product design for end users. 3D package technology of PoP (Package on Package) structure will be introduced for communication module and system control application.
